RDL SF-NP100A Network to 100 W Mono Audio Amplifier (70 V or 100 V)

The SF-NP100A is an audio power amplifier that receives four Dante (or AES67) network audio channels. It converts one of the Dante channels to a 70 V or 100 V constant voltage amplified output. The output provides 100 watts for a network digital audio level of 0 dBFS. The other three Dante audio channels are converted to RDL Format-A to feed additional amplifiers or other Format-A receivers. Input gain is set by the installer using a rear-panel single-turn potentiometer with an associated dual-LED VU meter calibrated to 10 dB below maximum power output. The SF-NP100A is equipped with an internal VCA for setting the amplifier output level. The REMOTE CONTROL RJ45 jack provides for the connection of an RDL D*-RLC10KM type remote level control. It is also possible to use the RJ45 jack to connect an external 10 kΩ potentiometer or a 0 to 10 Vdc control voltage. VCA control insures long term noise-free level adjustment. A selectable audio compressor is provided to add up to 15 dB additional
